Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle displays obstruct the driver's forward view and occupy unnecessary space due to their fixed size and position, especially with advancements in autonomous driving reducing the need for traditional instrument panels.
Innovation Solution
A deformable display device with a moving unit that can switch between flat and bent states, allowing it to adjust its shape and position based on vehicle status, using a flexible display panel, living hinge, and rigid ribs for support, enabling both linear and curved motions with a single motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display size is increased to provide more information, then the information output capability is improved, but the driver's forward view is obstructed
Solution Approach 1:
The display device transitions from a fixed state to a movable state, allowing it to protrude forward to expand display area when needed and retract to minimize obstruction when not in use. The movable unit enables the display to dynamically adjust its position along the forward direction, resolving the contradiction between providing adequate display area and maintaining unobstructed driver's view.
Solution Approach 2:
Instead of expanding the display area only in the lateral direction (which would increase obstruction), the invention utilizes the forward-backward dimension by allowing the display to protrude forward. This dimensional transition enables the display to occupy more screen real estate without proportionally increasing the lateral footprint that blocks the driver's view.
2Adaptability or versatility
If the display device is made deformable to adjust shape, then the adaptability to different vehicle statuses is improved, but the structural complexity increases
Solution Approach 1:
The display device incorporates a flexible display panel that can be bent deformed, allowing the screen to change its shape from flat to curved. This flexibility enables the display to adapt to different vehicle statuses and spatial requirements without requiring multiple rigid display units or complex mechanical transformation mechanisms.
Solution Approach 2:
The display structure transitions from a static rigid form to a dynamic deformable form. The flexible panel combined with the movable unit allows the display to dynamically adjust both its position and shape, enabling adaptation to different vehicle conditions while using relatively simple structural components.
3Area of moving object
If the display device protrudes forward to improve visibility, then the display area is expanded, but the space occupied in the vehicle is increased
Solution Approach 1:
The display device uses a movable unit that allows it to protrude forward only when needed for enhanced visibility. When the display is retracted, it occupies minimal space within the dashboard. This dynamic positioning enables the system to provide large display area during use while minimizing space occupation during storage or when not in use.
Solution Approach 2:
The flexible display panel can be folded or bent back onto itself when not in use, allowing the display structure to nest within a compact space. This nesting capability enables the display to provide adequate display area during operation while occupying minimal volume when retracted.
